Nvidia patents chip feature to spot duplicate memory data in cache

Patent drawing from the official filing.

Nvidia describes a processor design that checks its fast memory, known as cache, for data that is also stored in page tables. Page tables are lists that help the computer find where data is located in main memory. The invention uses circuits to identify these overlapping pieces of information within the cache.

Why it mattersThis is a low-level technical improvement that helps processors manage memory more efficiently, though it is unlikely to be noticeable to everyday users.

In the filing’s own words

Apparatuses, systems, and techniques to identify information in cache storage, where the information is also in one or more page tables. In at least one embodiment, a processor includes one or more circuits to cause information stored in one or more cache storages to be identified, where the information is also in one or more portions of one or more entries of one or more page tables.

What exactly they claim (claim 1)

1. A processor, comprising: one or more circuits to cause information stored in one or more cache storages to be identified, wherein the information is also in one or more portions of one or more entries of one or more page tables.
